Hi Product Hunt — I help build FrAIFlow Device Check.
Before a call or when an input feels wrong, it can be hard to separate browser permissions, device selection and the signal reaching the page. Check puts nine small checks in one place, with steps and troubleshooting beside each test.
For microphones, you can check input and use a short local recording for playback when the browser supports it. For controllers, you can inspect reported buttons and axes and sample the stick center. The site is available in 16 languages without an account.
The important limit: these are browser observations, not a hardware repair certificate. The center-offset sample is not a true hardware-deadzone measurement, and the tool does not claim trustworthy USB polling rate or end-to-end input latency.
Which device problem would you reach for this to investigate? We welcome concrete feedback, including where a browser limit needs a clearer explanation.
